feat: add PST_* flags and DolbraceState machine#325
Merged
Conversation
Set parser state flags during parsing of command substitutions, case statements, conditional expressions, array literals, heredocs, subshells, and regex patterns.
Track parsing state within parameter expansions to enable future context-sensitive quote handling. States include PARAM, OP, WORD, QUOTE, and QUOTE2 based on bash's DOLBRACE_* defines. State transitions occur when operators are encountered: - %#^, operators -> QUOTE state (single quotes special) - / operator -> QUOTE2 state (semi-special) - Other operators -> OP then WORD state
